Abstract
The method for design of a seismic-damping partition wall with variable-friction-force energy dissipation provided by the present application includes the following steps: building a bare frame model without considering lateral resisting stiffness of a partition wall, and calculating an inter-story shear force and an inter-story displacement of a structure under action of an earthquake; calculating an elastic strain energy of the structure, and determining an expected additional damping ratio provided by a seismic-damping partition wall for the structure; determining a friction damping force-sliding displacement curve of a single group of seismic-damping partition wall panels, and establishing a relational expression between a total friction hysteretic energy and a friction damping force and a target sliding displacement of the single group of seismic-damping partition wall panels, and the seismic resilience of the partition wall and the structure can be synergistically improved.
